Mission Report (Michael Studinger, Mission Scientist)

Today's flight is a new mission, designed to collect dh/dt measurements over Thwaites Glacier and its lower tributary channels. It re-occupies two ICESat-1 lines last flown in 2011, the inner “arch” last flown in 2009 and first flown in 2002 by the NASA-Chilean joint project, and an outer “arch” planned for 2010 but not yet flown.

LiDAR data collection started 11/21/2014 14:26 UTC and ended at 20:52 UTC. In total we collected 6.4 hours of LiDAR data. The weather in the survey area was perfect and we were also able to collect additional high altitude data over sea ice and land ice during transits to and from the survey area.
